If you change your plan or add-ons in the middle of a bill period, you’ll see partial-month charges or credits on your next bill.
Calculate your partial-month charges
For example, say you switch from a plan that costs $45 a month to one that costs $60. You make this change 10 days into your bill period.
- Figure out the daily charge for both your old and new plans. Bill periods are always 30 days, regardless of the calendar month, so divide your monthly charge by 30.
- Your old plan was $45 a month, which is $1.50 a day.
- Your new plan is $60 a month, which is $2.00 a day.
- Calculate the partial-month charges for your old and new plans. Multiply the daily charge by the number of days each plan was active during the bill period when you made the change.
- Your old plan, at $1.50 a day, was active for 10 days, which is $15.
- Your new plan, at $2.00 a day, was active for 20 days, which is $40.
- Determine your partial-month credits and/or charges. We bill monthly recurring charges in advance for most plans, but bill some in arrears (afterward).
- If you’re billed in advance: You already paid $45 for the full month of your old plan, so you’ll get a credit for the 20 days you didn’t use it. Multiply 20 days by $1.50 for a $30 partial-month credit. Your next bill will show a:
- Partial-month credit (-$30) for the 20 days you didn’t use your old plan
- Partial-month charge ($40) for the 20 days you used your new plan
- Full-month charge ($60) billed a month in advance for your new plan
- If you’re billed in arrears, your next bill will show a:
- Partial-month charge ($15) for the 10 days on your old plan
- Partial-month charge ($40) for the 20 days on your new plan
Good to know: You can avoid partial-month charges by scheduling your new plan or add-on to start on the first day of your next bill period.
